It is that distant years which did not take
Thy sovranty, recoiling with a blow,
Have forced my swimming brain to undergo
Their doubt and dread, and blindly to forsake
Thy purity of           and distort
Thy worthiest love to a worthless counterfeit:
As if a shipwrecked Pagan, safe in port,
His guardian sea-god to commemorate,
Should set a sculptured porpoise, gills a-snort
And vibrant tail, within the temple-gate.
